隔吸声屏障在变压器噪声控制中的应用

Application of Sound Insulation-absorption Barrier in Controlling Noise of Transformer

针对城市电厂变压器的噪声污染,以北京太阳宫燃气热电冷联供工程中应用的变压器噪声控制为例,通过分析研究变压器声源不同的频谱特性,并根据厂界噪声控制目标计算声源的超标贡献量和设计降噪量,开发设计了变压器降噪隔吸声屏障,针对变压器的低频噪声,设计特殊的隔吸声结构,并成功应用于工程实践,取得了理想效果。

Taking Beijing Sun Palace gas turbine power plant CCHP system in controlling the noise of transformer by using sound insulation–absorption barrier and in accordance with analysis and research of the spectrum characteristics of different source transformer,the paper calculates the noise reduction of source transformer.Good economic and the social benefits have been obtained.It’s good to create harmonious and friendly city between industry and environment.
